Multi Wrench

Winner - Spark!

(Team members: Hyuntae Kim, Hyuntae Roh, Seungmin Bak, Khanyoung Kong)When we are fixing things at home or repairing our cars in the garage we use many bolts. But the sizes of the bolts are all different so we have to prepare many ranches respectively according to each size. The task is inconvenient and the weight to carry around is too heavy. It's also difficult to match the standards of the bolts. If the measures are even slightly different the ranch rotates alone with the bolt staying in place. That is why we came up with this product. This product is a ranch that can be utilized in 5 different bolt measures. If you have just this one "Mr", you don't have to carry a big heavy ranch box around anymore, and your worries of the mismatching ranches and bolts are no more!
